11.9 x 9.4 x 3.4 cm. Botryoidal fluorites are rare from anywhere, so when these amazing purple ones were discovered in China, there was quite a stir made! We were lucky enough to get many of the best, and a good quantity of them compared to most dealers - there was not a lot around. Here is a largish plate with a bumpy botryoidal surface; these really glow a pretty purple if you put a strong light on or behind them.
5.7 x 3.9 x 3.4 cm. A cluster of super-clear fluorites from Naica, with glass-clear "windows" framed by frosty bevels. Some of the crystals have sharp little golden pyrite crystals deep inside!
5.4 x 3.9 x 3.3 cm. A cluster of tightly-intergrown crystals (to 1.5 cm across the middle) piled up on stark white contrasting quartz matrix.
3.8 x 2.6 x 2.3 cm. OLD-TIME and CLASSIC cubic Naica fluorite crystals with quartz matrix. Two, intergrown, limpid, green and colorless fluorite crystals form a very showy specimen. Theses water-clear beauties are pristine and are MUCH BETTER IN PERSON! Naica fluorites of this quality are seldom available.
4.5 x 2.1 x 1.3 cm. A superb pair of the deepest, most brilliant green Fluorites that I have ever seen from Erongo. Each crystal of the pair is about 1.5 cm, and the luster is excellent. And like the smaller, paler Fluorites on the specimen, there is a hint of purple on some of the faces. Ex. Charlie Key.
8.2 x 5.2 x 4.0 cm. A CLASSIC, OLD-TIME, fluorite specimen from the famous Weardale area of England. This very fine, two-sided, mounded piece features super lustrous and glassy, interpenetrating fluorite cubes to 2.1 cm on a sliver of limestone matrix. Typically, for many Weardale fluorites, the green cubes turn purple (natural fluorescence) in nearly all lighting conditions. The fluorites really are green! Very trivial damage, overall, to this fine old-timer. SUPER fluorescence. Old piece from workings either in the early 1800s or mid-1900s. Ex. Roman Gaufman and George Elling Collections.
2.0 x 1.6 x 1.3 cm. A beautiful, gem-like, water-clear, purple, cuboctahedral fluorite crystal from an UNCOMMON Argentine locality - Papachacra, Catamarca Province. The purple coloration and color intensity are in a very interesting swirl pattern. Some of the crystal faces are water-clear, while others are lightly frosted, giving a very nice effect. Ex. Dave Stoudt Collection.
16.9 x 13.4 x 6.4 cm. This was a short-lived find, and the specimens on the market disappeared quickly. These isolated crystals on sharply contrasting matrix are unique and instantly identifiable. Rarely were the octahedrons this large and sharp. This crystal measures 6 cm across and is undamaged.
16.4 x 10.9 x 3.7 cm. These purple fluorites are like JEWELS: razor-sharp and incredibly transparent, with gorgeous purple outlines. They are scattered aesthetically across the surface of the matrix. The crystals measure to 1.2 cm. This is a large specimen, and just wonderfully striking - a cut way above the usual Chinese material for sharpness and gemminess.
8.5 x 5.3 x 3.0 cm. From the exciting recent finds, this is the "classic" combo of green and purple tones, a knob of sharp crystals in excellent condition.
9.5 x 8.4 x 4.9 cm. A beautiful and sizeable specimen that combines gemmy purple fluorites with shiny-metallic, sharp arsenopyrites and transparent quartz crystals!
7.1 x 6.4 x 2.5 cm. These "fried-egg" fluorites have always been very popular with collectors - there are just not that many localities that produce botryoidal fluorites and these are smooth, silky and translucent, so they are particularly attractive. The fluorite balls here are nestled in crystalline quartz; the largest ball is 1.6 cm across.
7.9 x 6.9 x 6.4 cm. With the mines now closed, Elmwood specimens are getting harder and harder to find. Here you have a monster compound crystal of sphalerite, with individual distinct crystal forms measuring over 4 cm across and ornate, sparkly microfaces - with a cluster of purple fluorites to 1.4 cm. This is a classic Elmwood combo; sphalerite is an ore of zinc, and was the reason for the mining there.
15.4 x 12.2 x 11.9 cm. This is an OLD, unusual, very large specimen from Hardin County that is very uncommon to see on the market. What you have is these large, very spiky calcite scalenohedra (some of them do have tip cleaves), with a coating of whitish benstonite. The calcites have grown on a layer of teal-colored fluorite. Two layers of this fluorite sandwich a layer of brownish-yellow calcite. An old-timer! Ex. collection of Gary Hansen, noted Mid-west dealer until 1980s.
10.9 x 8.4 x 4.7 cm. Very unusual and pretty material from a little-known locality - these are frosty purple octahedra of fluorite (with micro-stepped Uncommon on the market, not the usual "by the ton" Chinese stuff!
